ALC was fabricated using cement, lime and quartzite by hydrothermal reaction. ALC has low strength and brittleness on account of inner pores. The studies for resolving these problems were driven by many researchers. Among these researches, the controls of quartzite fineness have been studied for unsuitable properties of ALC. This study experimented with variation of 90 ${mu}m$ residue for obtain good physical properties. It was found that 90 ${mu}m$ residue influenced on physical properties of ALC. The lower amount of 90 ${mu}m$ residue, the higher compressive and bending strength. But the continuing decrease of 90 ${mu}m$ residue did not cause the increase of strength. In order to application of these results in process, the states of process and hydrothermal products will be considered.
